- Qfactor.Q_unloaded(opt_res=None, A=None)[source]
Unloaded Q-factor Q0.
The value of the unloaded Q-factor Q0 cannot be measured directly but can be estimated from the measurement of the loaded Q-factor Q_L [MAT58] .
- opt_resNone or
OptimizedResult
. Default is None. Solution produced by the
fit()
method. If None, uses the solution previously calculated, if performed.- Afloat or None. Default is None.
Scaling factor as defined in MAT 58 [MAT58]. For reflection resonance type, can be set as None to use the magnitude of the fitted detuned reflection coefficient S_V
